Who owns the largest firms around the world?

In this research paper we evaluate how corporate control around the world is defined and which variables, related to a firm's characteristics and the countries' infrastructures, influences this. We find that there is a small number of countries where firms are widely held. The role of financial institutions seems to be different in civil and common law-based countries. While they seem to act as a monitor of management in common law-based countries, in civil law countries they act as a monitor of large shareholders. Finally, we find that firm's size is the most important determinant of ultimate owners.

Representações Masculinas Afro-americanas no Cinema: do Filme Liberal de Hollywood a “Boyz n the Hood”

O objecto de estudo deste trabalho é a construção da identidade masculina afro-americana, e representação desta no cinema liberal de Hollywood. Isolam-se três momentos de particular relevo: o período do cinema mudo antes da Primeira Guerra Mundial, os anos 1960-70 e por fim, a década de 1990. Traçar-se-á um percurso analítico que examina obras-chave da história do cinema comercial de Hollywood bem como manifestações do cinema independente afro-americano entabulando um diálogo permanente com o contexto histórico e social, nomeadamente a luta pelos direitos civis, a afirmação do Black Power, traduzida cinematograficamente na Blaxploitation, para finalmente se concentrar em Boyz n the Hood escolhido como sintomático de um impulso regenerativo das representações masculinas afro-americanas, sob forte ataque dos media populares nas últimas décadas do século XX.

Multi-Enzymatic Systems for Cleaning-up Synthetic Dyes from the Environment

Environmental pollution is one of the major and most important problems of the modern world. In order to fulfill the needs and demands of the overgrowing human population, developments in agriculture, medicine, energy sources, and all chemical industries are necessary (Ali 2010). Over the last century, the increased industrialization and continued population growth led to an augmented production of environmental pollutants that are released into air, water, and soil, with significant impact in the degradation of various ecosystems (Ali 2010, Khan et al. 2013).(...)

Norton de Matos, o improvável republicano: Um olhar sobre Portugal e o império entre Afonso Costa e Salazar

Discutir o papel político de José Norton de Matos (1867-1955) na galáxia republicana portuguesa entre 1910 e 1955 é o objectivo principal desta tese. A alteração do prisma de análise mais habitual quando se fala de Norton, do colonial para o político, foi acompanhada pela opção de privilegiar os seus escritos contemporâneos, em detrimento das muitas análises retrospectivas posteriormente publicadas, e de cotejar a sua voz com múltiplas vozes de Portugal e do império, entre muitas outras com que se cruzou. Tentámos compreender como é que um liberal como Norton, monárquico de tradição embora não de filiação, usa as suas credenciais coloniais para entrar na política republicana à boleia da polémica do cacau escravo e da Sociedade Portuguesa Anti-Esclavagista. Com a aproximação a Bernardino Machado, aos Jovens Turcos, à maçonaria e à facção do PRP dominada por Afonso Costa, insere-se na órbita democrática e afonsista e ganha o cargo de governador-geral de Angola. Aos africanos, cuja definição legislativa como uma categoria distinta da de cidadão (o indígena) antecipa em 1913, leva as luzes da educação laica e a liberdade de trabalho mas paradoxalmente convive com as escolas das missões e o trabalho forçado. A fibra de político que revela na gestão das tensões entre as elites coloniais e metropolitanas irá ser apurada como ministro da Guerra. Discutimos, em especial, o seu papel político num ambicioso projecto: transformar dezenas de milhares de portugueses, pobres, analfabetos e vindos de meios rurais com parcas simpatias republicanas, em cidadãos e soldados da República. A improvisação, que possibilitou que o Corpo Expedicionário Português fosse combater em França ao lado dos britânicos, teve o rasgo de asa e os problemas inerentes à megalomania que o caracterizava. No Verão de 1917, o prestígio com que regressa à capital após difíceis negociações com o governo de Lloyd George torna-o um sério concorrente de Afonso Costa embora com ele partilhe também o ónus da crescente impopularidade da guerra. Reencontrar-se-ão, após o exílio sidonista, na Conferência da Paz em Paris mas, ao contrário de Costa, que não regressará à política activa, Norton tornar-se-á o altocomissário mais marcante e polémico da nova República do pós-guerra. Após a queda do regime e dois novos exílios, será Norton de Matos a fazer os compromissos necessários para permanecer no país e, aí, combater a Ditadura Militar e o Estado Novo de Salazar. Quando, em 1931, consegue unir a oposição em torno da Aliança Republicano-Socialista, começa a impor-se como símbolo da I República. É com esse estatuto que integrará as frentes unidas antifascistas dos anos 40 que culminarão na sua candidatura à Presidência da República em 1948/1949. O modo como consegue fazer a ponte entre os vários ciclos e gerações da oposição e, simultaneamente, resistir às pressões para romper a unidade com os comunistas na fase mais crispada da Guerra Fria será uma última manifestação do seu talento político, cuja análise poderá ajudar a enriquecer o debate sobre essa realidade plural e multipolar que foi a galáxia republicana na primeira metade do século XX.

8-Phase Ring oscillator for modern receivers

The evolution of receiver architectures, built in modern CMOS technologies, allows the design of high efficient receivers. A key block in modern receivers is the oscillator. The main objective of this thesis is to design a very low power and low area 8-Phase Ring Oscillator for biomedical applications (ISM and WMTS bands). Oscillators with multiphase outputs and variable duty cycles are required. In this thesis we are focused in 12.5% and 50% duty-cycles approaches. The proposed circuit uses eight inverters in a ring structure, in order to generate the output duty cycle of 50%. The duty cycle of 1/8 is achieved through the combination of the longer duty cycle signals in pairs, using, for this purpose, NAND gates. Since the general application are not only the wireless communications context, as well as industrial, scientific and medical plans, the 8-Phase Oscillator is simulated to be wideband between 100 MHz and 1 GHz, and be able to operate in the ISM bands (447 MHz-930 MHz) and WMTS (600 MHz). The circuit prototype is designed in UMC 130 nm CMOS technology. The maximum value of current drawn from a DC power source of 1.2 V, at a maximum frequency of 930 MHz achieved, is 17.54 mA. After completion of the oscillator layout studied (occupied area is 165 μm x 83 μm). Measurement results confirm the expected operating range from the simulations, and therefore, that the oscillator fulfil effectively the goals initially proposed in order to be used as Local Oscillator in RF Modern Receivers.

Improving building technologies with a sustainable strategy

In recent years it has been noticed the progressive disappearance of vernacular sustainable building technologies all over the world mainly due to a strong urban rehabilitation process with modern technologies not compatible with ancient knowledge. Simultaneously new dwellings are needed all over the world and in this sense it was decided to study an ecological and cost-controlled building technology of monolithic walls that can combine the use of low carbon footprint materials, such as earth, fibres and lime using an invasive species: giant reed cane (Arundo Donax). This paper explains the development of this building technology through testing diverse prototypes.

The flow-performance relationship around the world

We use a new dataset to study how mutual fund flows depend on past performance across 28 countries. We show that there are marked differences in the flow-performance relationship across countries, suggesting that US findings concerning its shape do not apply universally. We find that mutual fund investors sell losers more and buy winners less in more developed countries. This is because investors in more developed countries are more sophisticated and face lower costs of participating in the mutual fund industry. Higher country-level convexity is positively associated with higher levels of risk taking by fund managers.

Fractional state space analysis of economic systems

This paper examines modern economic growth according to the multidimensional scaling (MDS) method and state space portrait (SSP) analysis. Electing GDP per capita as the main indicator for economic growth and prosperity, the long-run perspective from 1870 to 2010 identifies the main similarities among 34 world partners’ modern economic growth and exemplifies the historical waving mechanics of the largest world economy, the USA. MDS reveals two main clusters among the European countries and their old offshore territories, and SSP identifies the Great Depression as a mild challenge to the American global performance, when compared to the Second World War and the 2008 crisis.

Towards modification of Medicago truncatula epigenome: genome editing with engineered nucleases

Periodic drought is the primary limitation of plant growth and crop yield. The rise of water demand caused by the increase in world population and climate change, leads to one of the biggest challenges of modern agriculture: to increase food and feed production. De novo DNA methylation is a process regulated by small interfering RNA (siRNAs), which play a role in plant response and adaptation to abiotic stress. In the particular case of water deficit, growing evidences suggest a link between the siRNA pathways and drought response in the model legume Medicago truncatula. As a first step to understand the role of DNA methylation under water stress, we have set up several bioinformatics and molecular methodologies allowing the design of Clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 systems and the assembly of TALENs (transcription activator-like effector nucleases), to target both dicer-like 3 (MtDCL3) and RNA-Dependent RNA polymerase (MtRDR2), enzymes of the RNA-directed DNA methylation pathway. TALENs efficiency was evaluated prior to plant transformation by a yeast-based assay using two different strategies to test TALENs activity: Polyacrylamide gel electrophoresis (PAGE) and Single strand conformation polymorphisms (SSCP). In this assay, yeast cells triple transformation emerged as good and rapid alternative to laborious yeast mating strategies. PAGE analysis might be a valuable tool to test TALENs efficacy in vivo if we could increase TALENs activity. SSCP-based approach proved to be ineffective due to the generation of several false positives. TALENs and CRISPR/Cas9 system constructed and designed in this work will in the future certainly enable the successful disruption of DCL3 and RDR2 genes and shed the light on the relationship between plant stress resistance and epigenetic regulation mediated by siRNAs in M.truncatula.

The World Health Organization Multi-Professional Patient Safety Curriculum : implementation of key modules and its impact on patient safety knowledge, skills, and attitudes of medical students at the University of Algarve

ABSTRACT - Objectives: We attempted to show how the implementation of the key elements of the World Health Organization Patient Safety Curriculum Guide Multi-professional Edition in an undergraduate curriculum affected the knowledge, skills, and attitudes towards patient safety in a graduate entry Portuguese Medical School. Methods: After receiving formal recognition by the WHO as a Complementary Test Site and approval of the organizational ethics committee , the validated pre-course questionnaires measuring the knowledge, skills, and attitudes to patient safety were administered to the 2nd and3rd year students pursuing a four-year course (N = 46). The key modules of the curriculum were implemented over the academic year by employing a variety of learning strategies including expert lecturers, small group problem-based teaching sessions, and Simulation Laboratory sessions. The identical questionnaires were then administered and the impact was measured. The Curriculum Guide was evaluated as a health education tool in this context. Results: A significant number of the respondents, 47 % (n = 22), reported having received some form of prior patient safety training. The effect on Patient Safety Knowledge was assessed by using the percentage of correct pre- and post-course answers to construct 2 × 2 contingency tables and by applying Fishers’ test (two-tailed). No significant differences were detected (p < 0.05). To assess the effect of the intervention on Patient Safety skills and attitudes, the mean and standard deviation were calculated for the pre and post-course responses, and independent samples were subjected to Mann-Whitney’s test. The attitudinal survey indicated a very high baseline incidence of desirable attitudes and skills toward patient safety. Significant changes were detected (p < 0.05) regarding what should happen if an error is made (p = 0.016), the role of healthcare organizations in error reporting (p = 0.006), and the extent of medical error (p = 0.005). Conclusions: The implementation of selected modules of the WHO Patient Safety Curriculum was associated with a number of positive changes regarding patient safety skills and attitudes, with a baseline incidence of highly desirable patient safety attitudes, but no measureable change on the patient safety knowledge, at the University of Algarve Medical School. The significance of these results is discussed along with implications and suggestions for future research.

A segurança no terrorismo e na indústria dos eventos

Nowadays, safety and security regarding the tourism and events industries are a fundamental subject to society. Portugal’s tourism has significantly increased its number of visitors, whether due to the increasing number of cruisers docking in Lisbon, or due to visitors arriving by air, travelling the country from North to South and staying in the most varied accommodation units. Issues like human security and internal security of the different countries, even the security in the world, as development factors of a modern society, are discussed on a daily basis. On the contrary, few deal with tourism and major events security as being part of internal security, as well as the existing barriers tourism encounters to integrate the system for fighting terrorism. Although two distinct activities, they are complementary and may influence the country’s economy, provided that they can offer certainty to all actors involved. It is this substance that organised crime groups look for when planning terror acts. Therefore, as tourism can offer deception and shelter opportunities and events the theatre of a possible attack, those events assemble all the necessary conditions for an attack to achieve its goals.
